PROBLEM TO BE SOLVED: To provide a power storage device capable of suppressing damage to an insulating member when a nut is screwed into a shaft part.SOLUTION: In a secondary battery 10, a bolt-like external connection terminal 66 comprises a bolt head 67, and a shaft part 68 which protrudes from a bearing surface 67a of the bolt head 67, and into which a shaft part insertion hole 60a of a bus bar 60 can be inserted and a nut 70 can be screwed. A terminal connecting member 44 comprises a plate-like connection piece 46 including a through hole 46a through which the shaft part 68 of the external connection terminal 66 is inserted, and a plate-like fixing piece 47 electrically connected to a lead-out terminal 61 and fixed to a lid member 15 via an outside insertion member 57. Furthermore, the terminal connecting member 44 includes a plate-like locking piece 48 bent from the connection piece 46, and is in face contact with a head side surface 67b of the bolt head 67.SELECTED DRAWING: Figure 4 |
